| Abstract: | Stiffened columns are widely used in Lanzhou Olympic Sports Center.Based on the low-frequency cyclic load test of 16 steel reinforced high-strength concrete columns,the crack development mode and failure mode of the specimens were observed,and the restoring force characteristic curves of the columns were obtained.Then deformation capacity and hysteretic energy dissipation capacity of steel reinforced high-strength concrete column were quantitatively characterized by ductility coefficient and equivalent viscous damping coefficient,and the influence of shear span ratio,concrete strength,steel ratio,stirrup ratio and axial compression ratio on the seismic performance of steel reinforced high-strength concrete columns is discussed,the research results can provide data and theoretical support for the seismic performance of steel reinforced high-strength concrete columns and construction. |
